Configure the CData JDBC Driver for eBay in a Connection Pool in Tomcat

Connect to eBay data from a connection pool in Tomcat.

The CData JDBC Drivers support standard JDBC interfaces to integrate with Web applications running on the JVM. This article details how to connect to eBay data from a connection pool in Tomcat.

Connect to eBay Data through a Connection Pool in Tomcat

  1. Copy the CData JAR and CData .lic file to $CATALINA_HOME/lib. The CData JAR is located in the lib subfolder of the installation directory.
  2. Add a definition of the resource to the context. Specify the JDBC URL here.

    If you will be accessing your own account, you can generate an OAuthAccessToken from your developer account dashboard. You can also allow other users to securely access their own accounts.

    Both of these methods require you to create an application key set to obtain values for the following connection properties: AppId, CertId, DevId, and SiteId.

    The user consent flow additionally requires the RuName and CallbackURL.

    See the "Getting Started" chapter in the help documentation for a guide to using OAuth.

    Built-in Connection String Designer

    For assistance in constructing the JDBC URL, use the connection string designer built into the eBay JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

    java -jar cdata.jdbc.ebay.jar

    Fill in the connection properties and copy the connection string to the clipboard.

    You can see the JDBC URL specified in the resource definition below.

    <Resource name="jdbc/ebay" auth="Container" type="javax.sql.DataSource" driverClassName="cdata.jdbc.ebay.EbayDriver" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" url="jdbc:ebay:AppId=MyAppId;CertId=MyCertId;DevId=MyDevId;SiteId=MySiteId;RuName=MyRuName;CallbackURL=http://localhost:33333;InitiateOAuth=GETANDREFRESH" maxActive="20" maxIdle="10" maxWait="-1" />

    To allow a single application to access eBay data, add the code above to the context.xml in the application's META-INF directory.

    For a shared resource configuration, add the code above to the context.xml located in $CATALINA_BASE/conf. A shared resource configuration provides connectivity to eBay for all applications.

  3. Add a reference to the resource to the web.xml for the application. eBay data JSP jdbc/Ebay javax.sql.DataSource Container
  4. Initialize connections from the connection pool: Context initContext = new InitialContext(); Context envContext = (Context)initContext.lookup("java:/comp/env"); DataSource ds = (DataSource)envContext.lookup("jdbc/Ebay"); Connection conn = ds.getConnection();
